工厂位于城市的东郊,城市没有雨水道,厂的四周又没有河流和溝渠(距河流約10公里)。改建前,厂內空地很多,雨水系由地面自然散發和滲透排除。改建后,須排至市建設局确定的一塊荒蕪窪地上。窪地在厂东約兩公里左右,但該窪地不深,地势与工厂地面基本上是平坦的,雨水没有条件自然流入,故設計中考虑了雨水抽水站。
The factory is located in the eastern suburbs of the city. The city does not have rainy waterways. There are no rivers and ditches around the plant (about 10 kilometers from the river). Before the reconstruction, there was a lot of open space in the factory, and the rainwater was naturally distributed and infiltrated by the ground. After the reconstruction, it must be evacuated to a barren ground determined by the Municipal Construction Bureau. The ground is about two kilometers east of the plant, but the depression is not deep, the terrain and the ground of the factory are basically flat, and rainwater naturally flows in without conditions, so the rainwater pumping station is considered in the design.
